<p>
Did you come across [mod://Sys::Mmap]'s <code>hardwire()</code> method in your travels?
<p>
Just reading the synopsis for this function:
<pre>
hardwire(VARIABLE, ADDRESS, LENGTH)
Specifies the address in memory of a variable, possibly within a
region you've "mmap()"ed another variable to. You must use the same
precautions to keep the variable from being reallocated, and use
"substr()" with an exact length. If you "munmap()" a region that a
"hardwire()"ed variable lives in, the "hardwire()"ed variable will
not automatically be "undef"ed. You must do this manually.
</pre>
..and thought it just might be of use. Maybe try:
<code>
use Sys::Mmap;
# ...
Sys::Mmap::hardwire($address, 0x78000000, $kernel_size);
</code>
